Ulthera Results, Maintenance and Safety: Questions and Answers

Answers about what Ulthera can and cannot achieve, how long the effect lasts, how maintenance is planned, and how risks are kept low. Dr. Kim sets expectations from his own answers to patients and says plainly when a device is unlikely to be enough.

What Results to Expect

How long until Ulthera results show?

Results build gradually. Many people notice firmer skin or a slightly lifted contour at around 2 to 3 months, and improvement may continue for up to about 6 months as new collagen forms. Any tightness you feel in the early days is partly immediate contraction and swelling, which settle. Comparing photos taken before treatment and at about three months, in the same light, gives the clearest picture.

What results can I realistically expect from Ulthera?

Realistic results are modest: a slightly firmer jawline, a little less heaviness in the lower face or under the chin, a small lift of the brow, or skin that feels firmer. The change is subtle enough that others may notice you look fresher without being able to say why. It does not match what surgery can do, and in clinical studies some patients showed no visible improvement. Your age, skin quality and the degree of sagging all affect how much change appears.

Why can't I see any change after Ulthera?

There are several possible reasons. It may be too early, since the effect builds over about 2 to 3 months and sometimes up to 6. The main change in your face may be volume loss or skin quality rather than laxity, which Ulthera does little for, or the sagging may be beyond what a device can lift. Collagen response also varies, and Dr. Kim has written that energy devices depend on the body's own regeneration, which weakens with age.

Does Ulthera work for everyone?

No. In clinical studies a proportion of patients showed no visible improvement, and the response varies widely between people. Those with mild to moderate laxity, reasonable skin quality and realistic goals tend to respond better than those with advanced sagging, very thin or sun-damaged skin, or major volume loss. A careful examination before treatment is the most useful way to avoid an unrewarding result. Being told honestly that you are unlikely to benefit is also a useful outcome of a consultation.

How much lift does Ulthera actually give?

The lift is small, often described in millimeters rather than centimeters, for example a slight rise of the brow or a slightly crisper jawline. Much of the visible effect comes from firmer, tighter tissue rather than a large change in position. That subtlety is why it suits people who want to look refreshed rather than different. If you want a more pronounced change, surgery is more likely to deliver it.

Can one Ulthera session make a difference?

Yes, Ulthera is designed as a single-session treatment, and the result of one session develops over the following months. Whether that difference is visible to you depends on your starting point, the plan and your healing response. Some people choose to repeat it later to maintain or build on the effect. Judge a session at around three months before deciding on more. Early impressions during the swelling phase are not a reliable guide.

How should I judge my Ulthera result?

Use photos rather than memory. Take pictures before treatment and again at about three months, from the front and both sides, in the same lighting, at the same distance and with a relaxed face. Day-to-day changes in swelling, sleep and lighting easily hide or exaggerate a subtle result. Looking at the jawline angle and the area under the chin in profile is often the clearest comparison.

Can Ulthera make my face look worse?

It is uncommon, but some outcomes can be unwelcome. The main concern is a leaner or hollower look in an already thin face, which some people have reported after focused ultrasound, although the evidence is limited and mixed. Temporary unevenness from swelling, or rare nerve irritation affecting movement, can also occur. Conservative deep energy in lean areas and careful placement are the main ways to avoid these, as discussed in does Ulthera make your face hollow.

Does Ulthera improve skin texture and pores?

It can help a little. The 1.5 mm depth acts on the superficial dermis, and Dr. Kim has written that it extends treatment to pores and skin texture. However, texture, pores and fine lines are not Ulthera's main strength, and the effect is usually modest. Radiofrequency, lasers or skin boosters are often better suited when skin quality is the main concern.

Can Ulthera help acne scars?

Ulthera is not a treatment for acne scars. It firms tissue below the surface, which may make the skin feel slightly tighter, but it does not resurface the skin or release the tethered bands that pull scars down. Acne scars usually respond to treatments such as fractional lasers, needle radiofrequency or subcision. Active acne in the treatment area is also a reason to postpone Ulthera. Dr. Kim can explain which approach fits the type of scarring you have.

Will people notice that I've had Ulthera?

Usually not in an obvious way. Because the change develops gradually over months and is modest in size, people around you are more likely to think you look rested than to spot a treatment. There are no scars or visible marks once any redness or swelling has settled. If you prefer discretion, this gradual course is an advantage. Some people choose to tell no one and simply hear that they look well.

How Long It Lasts and Maintenance

How long does Ulthera last?

It varies, and sources describe different figures. Published descriptions often mention effects lasting around a year or more, while in his answers to patients Dr. Kim describes the effect of Ulthera as typically holding for around six months, and in another answer five to six months. His figures set conservative expectations. How long it lasts for you depends on age, tissue, weight changes, sun exposure, smoking and the plan, and aging continues throughout.

Why do estimates of how long Ulthera lasts vary so much?

Because "lasting" can mean different things. Some sources measure how long a change can still be detected in studies, while doctors answering patients often describe how long people feel the effect before wanting another session. The response also varies with age, the degree of sagging, the size of the treatment and lifestyle. Dr. Kim's own descriptions, around six months, reflect what patients tend to feel rather than what can be measured.

Does Ulthera last longer than Thermage?

Not according to Dr. Kim's own descriptions. In his answers to patients he describes the effect of Thermage as typically lasting around ten months to a year and that of Ulthera as around six months. The two work on different layers, Ulthera mainly on the deeper supporting layer and Thermage on the skin, so the more useful question is which layer needs treatment. Combining them lets each do the job it suits, as explained on the Thermage and Re2O page.

How often should I repeat Ulthera?

Many people are reassessed about once a year, and some go longer. Because Dr. Kim describes the felt effect as typically lasting around six months, some patients choose lighter sessions at shorter intervals instead of one large treatment a year. The right interval depends on your age, tissue thickness, laxity and how you responded last time. The decision is made after reviewing your face, not by the calendar.

Can Ulthera be done too often?

Repeating Ulthera before the previous session's remodeling has finished makes it hard to judge what is working and adds discomfort and cost without clear benefit. In lean faces, frequent deep treatment may also raise the concern about looking hollower over time. Allowing several months between sessions, and adjusting the plan to how you responded, is a reasonable approach. More is not automatically better.

Can I have Ulthera every six months?

Some people do, usually with smaller, lighter sessions rather than a full treatment each time. It can make sense when the effect fades sooner for you, which matches Dr. Kim's description of the felt effect lasting around six months. The plan for each session should reflect how your face responded to the last one, with particular care in lean areas. Ask whether a lighter combined approach, such as the one below, would suit you.

What is a light maintenance plan with Ulthera?

In one of his answers to patients, Dr. Kim describes a combination of 300 shots of Ulthera with 300 shots of Thermage as a good way to maintain results lightly, with Ulthera working on the deeper support and Thermage on the skin. He also notes that if the effect felt short or underwhelming, increasing the number of shots is an option to consider. The right combination depends on which layers need support. Combining treatments is discussed on the combination treatment page.

Do Ulthera results disappear suddenly?

No. The new collagen does not vanish at a set date; the effect fades gradually as aging continues and tissue slowly loosens again. Most people simply notice, months later, that the firmness has eased back towards where it was. Your face does not return to a worse state than it would have reached without treatment. Planning a review before the effect has fully faded helps if you want to maintain it.

Will my face sag more if I stop having Ulthera?

No. Stopping Ulthera does not cause faster sagging or rebound; the face simply continues to age at its natural pace. The collagen built by previous sessions gradually returns towards your baseline, but treatment does not create a dependency. Many people pause and restart treatments over the years without any harm. Lifestyle factors such as sun exposure and smoking affect aging far more.

Why do lifting treatments seem to stop working over time?

Dr. Kim has written that energy devices do not make collagen themselves; they stimulate the body's own regeneration, so as that capacity declines with age, the same treatment produces a weaker response. Sagging may also progress beyond what a device can lift, or the main change may shift from laxity to volume loss or skin thinning. A different layer may then need attention. He explains this in why lifting treatments seem to stop working.

What helps Ulthera results last longer?

Daily sun protection, not smoking, keeping a stable weight, good sleep and a sensible skincare routine all help preserve collagen. Large weight changes can undo a subtle lift by changing the volume the skin has to support. Treating the other layers that have changed, such as volume loss or thinning skin, can also make the overall result hold better. None of this stops aging, but it slows the loss.

Limits, and When Ulthera Is Not Enough

How much sagging is too much for Ulthera?

Ulthera works on tissue that is still roughly in place. When jowls hang clearly below the jawline, folds are deep because tissue has descended, or the neck has loose, hanging skin, the change a device can make is usually too small to satisfy. Dr. Kim, as a plastic surgeon trained in facial surgery, will tell you when you have reached that point. Options are discussed in when non-surgical lifting is not enough.

Can Ulthera remove loose skin?

No. Ulthera can firm and slightly tighten skin, but it cannot remove excess skin. When there is a genuine surplus, such as skin that folds or hangs along the jaw and neck or rests on the eyelashes, surgery is the way to remove it. Ulthera may still have a role before or after surgery for firmness, but it cannot replace excision. Dr. Kim can explain which group you belong to.

Does Ulthera work after major weight loss?

After large weight loss, the main problem is often a surplus of skin that has stretched and lost elasticity, together with lost volume. Ulthera can firm the tissue a little, but it cannot take up a large excess of skin or replace lost fullness. Combining approaches, or surgery where skin excess is marked, may be more effective. Waiting until your weight is stable before planning also makes sense.

Why did Ulthera work less well for me this time?

Several things can change between sessions. Your skin's regenerative capacity declines with age, which Dr. Kim has written weakens the response to energy devices. Weight changes, illness, sun exposure, a lighter plan or a different system and depth balance can all play a part. The main change in your face may also have shifted from laxity towards volume loss, which needs a different approach.

Can Ulthera get rid of deep wrinkles?

No. Deep wrinkles and folds come from a combination of lost volume, muscle movement, descended tissue and changes in the skin itself, and Ulthera addresses mainly one part of that. It can firm the surrounding tissue and soften fine lines a little. Depending on the cause, botulinum toxin, filler, collagen stimulators, radiofrequency or surgery may be more effective. Dr. Kim decides by identifying which layer causes the line.

Can Ulthera restore lost volume?

No. Ulthera tightens and firms; it does not add volume, and in a hollow face tightening can make the hollows look more obvious. Where volume has been lost, a collagen stimulator such as Sculptra, which rebuilds support gradually, or filler may be more appropriate. Many faces need both firming and volume, planned together. See the Sculptra page.

What does Dr. Kim do if Ulthera is not the right choice?

He says so and explains why. If volume loss is the main problem, he may suggest Sculptra; if the skin itself has thinned, Thermage with Re2O; if tissue has descended too far, surgery. He does not perform surgery at Violacell, but as a plastic surgeon trained in facial surgery he can explain what surgery would involve and whether it suits you. The aim is the right treatment for the layer that has changed.

Is a modest Ulthera result worth having?

That depends on what you want. For people who value looking a little firmer and fresher with no incisions and little downtime, a modest result can be worthwhile. For people hoping for a clear, visible lift, it may be disappointing, and knowing that in advance matters. Discussing what change is realistic for your face before treatment is the most reliable way to avoid regret.

Can Ulthera be used as a step before a facelift?

Some people use Ulthera while sagging is still mild and move on to surgery later, when the change a device can make is no longer enough. Ulthera does not make a later facelift more difficult in general, but your surgeon should know about previous treatments. It is also not a way to delay a facelift indefinitely. The point at which surgery becomes the better option is discussed on surgery or non-surgical lifting.

Side Effects and Safety

Is Ulthera safe?

Ulthera has a long track record and is generally considered safe when performed correctly, with most side effects mild and temporary. Like any treatment that heats tissue, it carries risks, including rare nerve irritation, burns or marks. The main safeguards are choosing the right depth for each area, avoiding bone and higher-risk nerve zones, and keeping the transducer in even contact with the skin. Being honest about your medical history also matters.

What are the side effects of Ulthera?

Common effects are redness, mild swelling and tenderness, usually settling within hours to a few days, with tenderness along the jaw sometimes lasting a few weeks. Less common effects include bruising, tingling, numb patches and temporary welts or line-shaped marks. Rare effects include temporary nerve weakness, such as an uneven smile, and burns or lasting marks. Practical recovery advice is on the pain and recovery page.

Can Ulthera damage facial nerves?

Temporary nerve irritation is a recognized but rare risk. Reported cases of weakness, for example in the branch that moves the lower lip, have usually recovered over weeks to months. The risk is reduced by knowing where nerves typically run, such as the branch crossing the temple and the branch near the jaw edge, and by lowering energy, using shallower depths or avoiding those zones. Dr. Kim brings this surgical anatomy to the plan.

Can Ulthera cause burns?

Burns are rare. In one of his answers, Dr. Kim notes that the chance of a burn with Ulthera is low, because the energy is focused beneath the surface. Risk rises if the transducer is not in even contact with the skin or if energy is placed too superficially for the tissue. The image before each pass helps confirm contact and depth. If a blister or burn does appear, contact the clinic promptly so it can be cared for properly.

Can Ulthera leave scars?

Lasting scars are rare. Ulthera does not cut the skin, and most marks that appear, such as welts or line-shaped redness, fade within days. In uncommon cases a burn can leave a mark or temporary darkening, more likely with poor contact or energy placed too superficially. People who form keloids or hypertrophic scars easily should mention this beforehand. Prompt care of any surface burn reduces the chance of a lasting mark.

Does Ulthera cause fat loss in the face?

The treatment is not designed to remove fat, and the evidence on fat loss is limited and mixed. Some people with lean faces have reported looking hollower after focused ultrasound, possibly where deep energy was placed in areas with little fat. For this reason, in slim faces Dr. Kim places deeper energy cautiously and may suggest volume treatment instead or alongside. If you are concerned, say so at consultation.

Is Ulthera safe near the eyes?

Treatment near the eyes stays outside the bony rim of the eye socket, where the bone protects the eye, and uses superficial depths on very thin skin. The eyelids themselves are not treated with Ulthera. Within those limits, treatment near the brow and the outer eye area is commonly done. Tell the doctor if you have had eye surgery or have an eye condition. Contact lenses can be removed beforehand if you find that more comfortable.

Is Ulthera on the neck safe for the thyroid?

Neck treatment stays away from the midline over the windpipe and thyroid gland, and from the major blood vessels at the side of the neck. Lines are placed on the parts of the neck where the skin and muscle can be treated safely, with depths chosen for the thinner neck tissue. If you have a thyroid condition or nodules, mention it beforehand. The image helps confirm the tissue under each placement.

Is it safe to have Ulthera many times over the years?

Ulthera has been used for well over a decade, and repeated treatment spaced appropriately is common practice without known cumulative harm in typical use. The main considerations with repeated sessions are allowing enough time between them and watching for any leaner look in thin faces. Each session should be planned from how your face looks now, not from a fixed routine. Long-term data continue to grow.

Can Ulthera cause pigmentation?

Pigment change is uncommon with Ulthera because it does not target pigment and focuses energy beneath the surface. Temporary darkening can occur after a burn or surface irritation, and it is more likely in skin prone to hyperpigmentation. Sun protection after treatment reduces the risk. Mention any history of pigmentation problems so the plan can account for it.

How does Dr. Kim reduce the risks of Ulthera?

He plans each treatment from the live ultrasound image and from palpation, checking tissue thickness, fat and bone before choosing a depth. He keeps energy off bone, treats more cautiously in thin areas, and reduces or avoids energy along the typical paths of facial nerves, drawing on his training in facial surgery at Chonnam National University. He also asks about previous treatments, medicines and conditions. His approach is described on why Dr. Kim for Ulthera.

Medical Conditions and Previous Treatments

Can I have Ulthera while pregnant or breastfeeding?

Ulthera is generally postponed during pregnancy, because its safety has not been studied in pregnant women and there is no medical need for it. During breastfeeding, many clinicians also prefer to wait, particularly if medicines or sedation would be involved. Since the treatment is elective, delaying it carries no downside. Discuss timing once you have finished breastfeeding. If you might be pregnant, say so before any treatment or medicine is given.

Can I have Ulthera with a pacemaker or metal implant?

A pacemaker, defibrillator or other implanted electronic device, or a metal implant in or near the treatment area, needs individual assessment and may mean Ulthera is not appropriate in that area. Tell the clinic about any such device or implant, including facial plates and screws from previous surgery. The doctor can then decide whether to treat, adjust the areas or recommend another approach. Bring details from your specialist if you have them.

Can I have Ulthera if I take blood thinners?

Often yes, but tell the clinic in advance. Blood-thinning medicines such as aspirin, clopidogrel or warfarin, and supplements such as fish oil, vitamin E and ginkgo, increase the chance of bruising. Never stop a prescribed blood thinner without talking to the doctor who prescribed it, because the reason for taking it usually matters more. The plan and comfort measures can be adjusted, and you can expect a higher chance of bruising.

Can I have Ulthera if I have rosacea or sensitive skin?

Usually yes, as Ulthera focuses its energy beneath the surface. Sensitive skin may stay red a little longer, and heat can trigger flushing in rosacea, so treatment should be avoided during a flare. Gentle aftercare and avoiding heat afterwards help. If the main concern is redness or visible vessels, other treatments may be more useful.

Can I have Ulthera if I have acne?

Active acne in the treatment area is a reason to postpone Ulthera until it is under control. Inflamed spots, cysts or open lesions should not be treated over. Mild, occasional breakouts elsewhere on the face usually do not prevent treatment of other areas. If you are taking isotretinoin, mention it, as some clinicians prefer to wait after finishing a course.

Can I have Ulthera if I have an autoimmune condition?

It depends on the condition, how active it is and which medicines you take. Some autoimmune and connective tissue conditions, and medicines that suppress the immune system, can affect healing and how the skin responds. Ulthera may still be possible, but it should be discussed with the clinic and sometimes with your specialist. Treatment is usually avoided during an active flare involving the skin.

Can I have Ulthera after facial surgery or fat grafting?

Often yes, once healing is complete, but the doctor needs to know exactly what was done and when. Surgery and fat grafting change the tissue layers, add scar tissue and may leave implants, plates or grafted fat that affect how energy should be placed. In grafted areas, energy is often kept conservative to protect the transferred fat. Palpation and the image help map these changes.

Can I have Ulthera if I form keloids?

Usually yes, because Ulthera does not cut the skin, but a tendency to keloids or thick scars should be mentioned. Any burn or deep surface irritation could, in theory, heal with a thicker scar in someone prone to it. Energy and depths near the surface may be chosen more cautiously. Keloid-prone areas such as the jawline and chest deserve particular care.

Can I have Ulthera if I have diabetes?

Many people with well-controlled diabetes can have Ulthera. Poorly controlled blood sugar can slow healing and reduce sensation, which makes it harder to notice excessive heat during treatment. Tell the clinic about your diabetes and any nerve problems. Treatment may be postponed if control is poor. Keeping your usual meals and medicines on the day of treatment also helps avoid low blood sugar during a long session.

Is it safe to have Ulthera after cancer treatment?

Ulthera is not used over areas affected by an active skin cancer or recent radiation treatment. After cancer treatment, timing depends on the type of cancer, the treatments received and your specialist's advice. Radiation in particular changes how tissue heals. Discuss your history openly, and expect the clinic to ask for your specialist's view if needed.
